ANSYS

The HEC currently hosts several components of the commercial Ansys package, with licenses supplied by the Engineering Department.

A sample serial job script for cfx5solve

Cfx5solve batch jobs may be run by creating a batch job control script i (such as the example below, which uses ansys_job.com):

#!/bin/bash

#SBATCH -p serial
#SBATCH --mem=4G

source /etc/profile
module add ansys/21.2

echo $MYHOSTLIST

cfx5solve -batch -def mymodel.def

A sample parallel job script for cfx5solve for Ansys 19 or earlier

For models suitable for parallel running, the following parallel job i template can be used, which runs on 2 of the 16-core compute nodes:

#!/bin/bash

#SBATCH -p parallel
#SBATCH --nodes=2
#SBATCH -C node_type=10GethAny
#SBATCH --exclusive

source /etc/profile
module add ansys/17.2

echo $MYHOSTLIST

cfx5solve -batch -def mymodel.def \
  -par-dist "$MYHOSTLIST" -start-method "HP MPI Distributed Parallel"

A sample parallel job script for cfx5solve for Ansys 20 or later

For models suitable for parallel running, the following parallel job template can be used, which runs on two of the 16-core compute nodes:

#!/bin/bash

#SBATCH -p parallel
#SBATCH --nodes=2
#SBATCH -C node_type=10GethAny
#SBATCH --exclusive

source /etc/profile
module add ansys/21.2

echo $MYHOSTLIST

cfx5solve -batch -def mymodel.def -par-dist "$MYHOSTLIST" \
    -start-method "Open MPI Distributed Parallel"

where mymodel.def is the name of the Solver Input File. Ansys uses MPI for parallelism - see Using the Message Passing Interface (MPI) on the HEC for more details on MPI job scripts.

A sample parallel job script for fluent for Ansys 19 or earlier

For models suitable for parallel running, the following parallel job template can be used:

#!/bin/bash

#SBATCH -p parallel
#SBATCH --nodes=2
#SBATCH --exclusive
#SBATCH -C node_type=10Geth64G

source /etc/profile
module add ansys/19.1

fluent 3ddp -g -slurm -t${NSLOTS} -pdefault -i runjob.jou

Where runjob.jou is the name of your fluent journal file. Ansys uses MPI for parallelism - see Using the Message Passing Interface (MPI) on the HEC for more details on MPI job scripts.
